Description

Technical field:

[0001] The utility model belongs to the technical field of bracket drilling positioning, and more specifically relates to a drilling rotary tool. Background technology:

[0002] The brackets are mostly produced by casting. In order to facilitate the later assembly and fixation of the brackets after casting and cooling, multiple fixing holes need to be evenly opened on the formed brackets, so as to facilitate the later assembly of the brackets. When holes are opened on the surface of the formed brackets, most of them are positioned by positioning tooling to assist the hole opening operation of the brackets.

[0003] The existing bracket has multiple surfaces that need to be drilled. The scissor arm is an important component for assembling the scissor-type lifting device. There are three surfaces on the scissor arm that need to be drilled. Currently, when the scissor arm is drilling, after processing one side, the scissor arm needs to be manually flipped over and aligned before drilling. In addition, it is easy to offset during the processing, resulting in poor accuracy, which affects the subsequent processing of the scissor arm. Utility model content:

[0004] In order to solve the above problems and overcome the shortcomings of the prior art, the utility model provides a drilling rotary tool;

[0005] The first technical problem to be solved is that deviation is likely to occur during the machining process, resulting in poor precision and affecting the subsequent machining of the scissor arm.

[0006] The specific technical solution of the utility model to solve the above technical problems is as follows: the drilling rotary tooling comprises a working platform;

[0007] A drilling die for pre-positioning the pre-drilling points of the bracket is arranged on the upper end surface of the working platform, a preset number of holes matching the pre-drilling points of the bracket are opened on the drilling die, and the drilling die is clamped on the working platform;

[0008] The working platform is provided with a fixing seat and a preset number of clamping assemblies for clamping the drilling mold; the fixing seat is installed on the end surface of any end of the working platform, and the clamping assembly includes a vertical adjustment plate for clamping the drilling mold in the vertical direction, a horizontal adjustment plate for tightening the drilling mold in the horizontal direction, and a clamping seat for tightening with the horizontal adjustment plate; the vertical adjustment plate is arranged above the drilling mold, and the horizontal adjustment plate and the clamping seat are respectively arranged on both sides of the drilling mold;

[0009] A first threaded hole is formed in the horizontal direction on the horizontal adjustment plate, and a tightening bolt of the tightening bracket is threadedly connected to the first threaded hole;

[0010] A second threaded hole corresponding to the first threaded hole is formed on the side of the drilling mold;

[0011] The upper end surface of the drilling die is provided with a preset number of third threaded holes in the vertical direction through which the tightening bolts tighten the bracket;

[0012] Adjusting screws for driving the vertical adjusting plate to clamp the drilling die are installed at both ends of the vertical adjusting plate, and adjusting nuts are arranged on the adjusting screws.

[0013] Furthermore, the locking components are provided in three groups, which are respectively arranged at the front end, the middle part and the rear end of the working platform.

[0014] Furthermore, the engaging assembly is mounted on the end surface of the working platform by means of bolts.

[0015] Furthermore, a U-shaped groove for easily disassembling the adjusting screw is provided at one end of the vertical adjusting plate.

[0016] Furthermore, both ends of the working platform are rotatably connected to the frame, a rotating shaft is fixedly provided at the end of the working platform, a rotating shaft motor matching the rotating shaft is fixedly provided on the frame, and the rotating shaft is key-connected to the rotating shaft motor.

[0017] The beneficial effects of the utility model are:

[0018] One advantage of the utility model is that a drilling mold for pre-positioning the pre-drilling points of the bracket is provided on the working platform. The drilling mold cooperates with the clamping assembly to achieve fastening of the bracket while accurately positioning the pre-drilling points of the bracket, thereby ensuring the precision and accuracy of the processing, increasing the accuracy rate of the assembly holes, and solving the problem in the prior art that the bracket is offset during the processing, resulting in poor accuracy and low work efficiency.

[0019] One advantage of the utility model is that the working platform is connected to the frame by a rotating shaft and a rotating shaft motor in a manner that allows it to rotate around the rotating shaft; this structure enables the frame to drive the working platform to rotate by means of shaft positioning. Compared with the prior art, it is necessary to manually lift and flip the bracket before drilling, and during the flipping process, it is necessary to find the drilling point again, which is quite troublesome, and the drilling efficiency and accuracy are poor; adopting this structure to drill holes on multiple sides of the bracket makes it convenient for workers to find drilling points, thereby improving work efficiency and processing accuracy.
